ABSTRACT:
An electromagnet actuator has an E-shaped core for coupling magnetic flux between the core and a blade of a hoistway rail. A pair of coils wound on the core provide the flux in such a way as to produce both side-to-side and front-to-back forces that can be controlled by varying the current to the pair of coils in each actuator on opposite sides of the car.
